Replace blank bracket or RS232/485 I/F Board (TWB-02350) next to connector board (TWB-02310)
with analog output I/F board (TWB-02370).
Set SPEC 58 is 1000 to enable Analog Output function, while set 0000 to disable it. Hardware jumper
setting selects current or voltage mode, refer to silk screen on PCB. Only one output mode is
available at the same time.

ANALOG OUTPUT BOARD CALIBRATION
CALIBRATION PROCEDURE
Analog output value should be 4mA at Zero Point and 20mA at Capacity Weight. If the output
values are not the appropriate value, adjust those by the following procedure.
ZERO – Rezeroing
SPAN1 – Fine adjustment
SPAN2 – Coarse adjustment
Before startup, precautions have to be taken to ensure all potentiometers are not overturned. After
the check has been done, proceed with setup.
The procedure can be accomplished as follows:
STEP 1 – Zero offset adjust
Load all zeros, then tune the “ZERO”.
For the voltage mode, adjust to 1V, while for the current mode, on the other hand, adjust to 4mA.
STEP 2 – Coarse adjustment
Load all ones, adjust the “SPAN2” which constitutes the varying of the operating range. Careful
tuning has to be taken, as it is very sensitive. It is termed as coarse adjustment because it varies a
wider range. For the voltage mode, adjust to approximately 8.99V for the 0-10V range and
approximately 4.2V for the 0-5V range. For the current mode, adjust to approximately 19.99mA.
STEP 3 – Fine adjustment
Adjust “SPAN1” which constitutes in fine adjustment to the actual full span. This has to be done
after adjusting “SPAN2”.
This adjustment algorithm is iterative, therefore, STEP1 to STEP3 has to be repeated until
convergence is obtained.

DI-80 Limited Warranty
Rice Lake Weighing Systems (RLWS) warrants that all RLWS equipment and systems properly installed by a
Distributor or Original Equipment Manufacturer (OEM) will operate per written specifications as confirmed
by the Distributor/OEM and accepted by RLWS. All systems and components are warranted against defects
in materials and workmanship for two (2) years.
RLWS warrants that the equipment sold hereunder will conform to the current written specifications
